I love this idea, but is that Sucker Punch on a Choice set? Eeeewww. Being locked into Sucker Punch is awful. Also, Magnet Rise on Magneton? I feel like it's not that useful. Perhaps switch for HP Fire? Just some thoughts.
Well I've already explained that most pokemon that use Ground type moves in the tier are slower then Magneton therefore it has it's uses, you could switch it out for thunderbolt if you're more worried about fire and fighting type attacks.
If you're using HP-fire you have to drop HP-ice, therefore having inferior coverage, HP -fire really only hits durant and Ferroseed.
Although both are relatively common in RU, but Durant is likely to move up to UU from the June Statistics.
And most ferroseed run full support in the tier, therefore setting up a sub while accumulating SpA boost from Charge beam is usually a better option over HP-fire, even if it does attack it's unlikely to break your sub.
You could run HP-grass to catch the odd Gastrodon and Quagsire off guard but then you're walled by rotom-c (Elec/grass), Galvantula (Elec/Bug) and the many grass/poison types.
As for CB Suckerpunch, What blarajan said.
